POTATO HEALTH BENEFITS, NUTRITION VALUES
|
In 18th century, potatoes were introduced to North America via Irish
immigrants, however their origin is South America. Over 7,000 years ago,
potatoes were first cultivated in the Andes Mountains. Many kinds of potatoes
are seen today, but the most common of these are the russet, round white,
and the red potato. Potatoes are tough and durable, store well, and have an
impressive nutritional content including being a rich source of fiber, potassium
and vitamin C. Like other fruits and vegetables, potatoes are a low calorie
food and are free of fat, cholesterol, and sodium. However, the leaves and
stems of a potato plant are poisonous and may cause illness when ingested.

101 cases of gallstones suggests a significant reduction in odds ratio with the
consumption of sweet potato among vegetables. [1]

was found to be effective binder for cholesterol in a vitro study. [4]
Availability, Selection and Storage
Potatoes are grown across the United States and are available year round.
Store potatoes in a cool, dry place. Sunlight can cause the skin to turn green;
if this occurs the skin must then be peeled off before consuming. Most of the
nutrients are contained right below the skin, so avoid peeling when possible.
Besides fresh potatoes, other forms are often available as well, including
• Refrigerated pre-cut fresh potatoes
• Frozen potatoes
• Canned potatoes
• Dehydrated potatoes
When choosing potatoes, be sure they are firm, smooth, and the color they
are supposed to be. Softness, a green tinge, or wrinkly skin may indicate a
potato that is past its prime.
Preparation
Potatoes should be thoroughly washed with clean tap water and scrubbed
lightly before preparation. Any sprouts or eyes growing from the potato
should be cut out. The skin can be removed or
left on depending on use.
Common methods of preparation include boiling, baking, microwaving,
mashing, frying and grilling. Consuming baked and grilled potatoes with the
skin left on provides the most nutrients.
